The Fantastic Four #37 (1965)

Susan Storm, whose father died last issue, wants to get some payback so the team goes to the Skrull’s home planet and beat up a whole bunch of folks before the responsible Skrull is killed. The FF don’t actually execute him, but it’s their efforts that lead to his death.

And there’s a wedding rehearsal, too.
